Use Cases for Li-Fi in Automotive and Transportation

High-speed, short-range Li-Fi (Light Fidelity) bidirectional connectivity technology, based on visible light, infra-red, and near ultraviolet communication, is a closer reality with the first reported successful live tests performed by Estonia-based startup Velmenni. The technology is based on modulating light sources at nanosecond intervals. A pilot was set up in an office building and industrial contexts in Tallinn for use cases, such as a smart lighting and office internet access. Speeds of up to 1Gbps were demonstrated, with orders of magnitude faster than Wi-Fi. In lab conditions even higher bandwidths have been obtained. Laser-based lighting could push attainable throughput higher still.
